Accessibility features in the Apple TV app
The Apple TV app 
supports these accessibility features:
Closed Caption and SDH support: The Apple TV app supports closed captioning, so those who are deaf or hard of hearing can fully enjoy new TV episodes and thousands of movies. Just look for the CC or SDH icon when you’re browsing movies or TV shows. You can even customize captions with special styles and fonts. See Use subtitles and captioning in the Apple TV app.
Audio Descriptions: Audio descriptions provide an explanation of important onscreen action and content in movies and TV shows. See Use audio descriptions in the Apple TV app.
Bold Text: Choose Bold Text to make text easier to read throughout the Apple TV app interface. See Display bold text in the Apple TV app.
VoiceOver: The Apple TV app supports the VoiceOver screen reader. Available in the languages supported by your smart TV’s screen reader, VoiceOver tells you exactly what’s on your TV screen and helps you choose commands. See Use VoiceOver in the Apple TV app.
Increase Contrast: Increase contrast on the screen by reducing the transparency of background elements on movies and TV show pages, menu tabs, and more. You can also use a high-contrast cursor to better delineate the focused content. See Increase Apple TV app screen contrast.
Reduce Motion: Turn on this setting to visually simplify some screen actions—such as screen animations. See Reduce screen motion in the Apple TV app.
Not all of these features are available on all smart TVs or streaming devices. See your smart TV or streaming device user guide for more information.
